Trying out a brand new Oceanic Geo 2.0 -- can't sync

[Linus Torvalds]

Try doing

   rpm -e --nopdeps ModemManager

Followed by killing that silly daemon.

Or something similar. ModemManager is some crazy sh#t, and thinks all
serial ports are modems and tries to talk to them. That is usually the
reason for the "Device busy" errors.

It *might* also confuse the dive computer itself with silly probing IO, but
the other error you see might just also be due to some new protocol version
or whatever. But trying to get rid of modem manager first is worth a try,
just in case.
